New Tectonics 2016 Revised (V)

New Tectonics 2016 Revised (V)

I will comment here an image I published last year (I noticed yesterday while re-reading my posts, that in some cases there are inconsistencies of time because of the different way for date formats between European and American date functions for the different systems, so 1900/04/05, for instance, is read by apps, and other automated parsers as the fourth of May (American) instead of (the fifth of April) so pay attention to context or ask me if you have any doubt about dates, I use European convention, so 2016/01/08, is January the eighth):

I’ll translate the texts in Spanish, for the general convenience of the world (well… except, perhaps, for some Astunglish or other language or dialect speakers… 🙂 who will have to wait until I have time enough to translate, which I would do at once, if it wasn’t because if I did, I would not end this along with other, from a long time ago, pending series of posts… [you can offer yourselves as translators, and I’ll see what I can do about it…]).

The image above, is an extended analysis for the pencil drawn world map in one of my papers of the previous post. On the top left corner there is a list of places and numbers, the numbers on the right of the names for the locations are for years, so 1 is one year, and 1000 is one thousand years. The list has numbers on the left also. These numbers are for the locations on the world map.

This world map is a Fuller’s projection. It distributes areas onto equally set triangles, if you print it and fold you’ll get a closed volume which would fit into a spherical shell on the outer side (outside) and would enclose also  a spherical core on the inner side (inside), just as a soccer/football ball is made with hexagonal and pentagonal patches of matter, but in this case are all equilateral triangles, so there is distortion, but is equally distributed all over the map.

‘A well known massive extinction for megafauna, the Holocene extinction (extinction event for Quaternary), happened at the end of the last glacial period: the Würm glaciation …

[for which it is interesting to watch at that en.wikipedia’s article image, and notice there is a parallel evolution on s2 hybridization s2-H, and s2 + p6+ d10  hybridization s18- O (which, by the way, can also be understood as 16+2) isotopes, along with this other image from ice cores (rods taken out for analysis) sediments concentrations, (years BP= years before PRESENT, permille = parts per thousand, different from, ppmv= parts per million Vostok), in this case the image is for temperature in centigrade degrees, carbon dioxide, and dust, which I’ll comment in some forthcoming post (for the general enlightenment of everybody (?)  !)].

… and eliminated many of the giant animals at the timer, such as furry mammuth (those giant ancestors of the elephants) , in America (the places into the red thin framed rectangles are  those for which datation is more inaccurate), and the North of Europe and Asia. The extinction wave has been atributed to hunting, the climate change, diseases, a possible extraterrestrial impact…

However, this last pulse of extinction near the end of Pleistocene was only one of a series which had took place during the latest 50000 years on the vast majority on Earth, being Africa, and the South of Asia, the less affected. These last areas suffered a gradual loss , particularly in slow movement species (like terrestrial turtles), in the last millions of years.

Out of the continental territories of Africa, Europa and Asia, these extinctions of megafauna followed a distinctive pattern from land to land that occurred after the human expansion (which feeds the hunting theory) into regions previously unhabited on the globe, and this does not correlate with the climate history (that can be visualized with graphs on distinct element and sediments concentrations over geolocical periods of time, such as markers of marine oxigen isotopes or carbon dioxide levels into the (on sediments trail of) atmosphere.

Australia was first affected near 45000 years ago, followed by Tasmania 41000 years ago (after the formation of a terrestrial bridge from Australia, 43000 years ago);  Japan, apparently (along with other considerations, it is a highly ferromagnetic, tectonic, and seismic active area of our planet, so, think twice: elements decay there much faster than in other places because of its natural geolocation features), 10000 years ago, Northamerica 13000 years ago, South and Central America 500 years afterwards (12500 years ago), Cyprus 10000 years ago, the Antilles 6000 years ago, New Caledonia and nearby islands 3000 years ago, Madagascar 2000 years ago, New Zealand 700 years ago, Mascarene Islands (northward, from Madagascar into Indian Ocean) 400 years ago, and Komander Islands 250 years ago.

Almost all isolated islands in the world could provide similar examples of extinctions occurred after the Homo Sapiens Sapiens [(1): See joke at the end of the paragraph] arrival, although many of these islands, like Hawaii, never had had terrestrial megafauna, and hence into those places the extinct fauna was less.

[JOKE: A child asks to their mum:

(‘child’ is for ‘girl’ and also for ‘boy’, like ‘baby’, in English when the noun is not defined in number or gender, plural pronoun is used although it be referred to a singular subject:
subject n, sujeto nm
(gramática: realiza la acción) (grammar)
El sujeto de la oración “yo como manzanas” es “yo”.
The subject of the sentence “I eat apples” is “I”.
and ‘child’ has an irregular plural: ‘children’, also for both genders).

Child: Mum, is it true that we come from monkeys?

Mum: I dont’know hun, your father never wanted to introduce me to his family.]

Are you really expecting me to write a treaty on hominidization also? 🙂

[Remember there are also some cases for pieces of land that, as is the case for Iberian Peninsula, were not joined to the neighboring lands as a whole, but were adjoined after a tectonical movement, so in some cases, should be studied as what they were then, islands, or fragments of other continental crusts].

(It is going to be a long post this one… beware of updates, and this is all for today updates, I’ll continue in some other moment).

I am a teacher of English who started to write this blog in May 2014. In the column on the right I included some useful links and widgets Italian is another section of my blog which I called 'Cornice Italiana'. There are various tags and categories you can pick from. I also paint, compose, and play music, I always liked science, nature, arts, language... and other subjects which you can come across while reading my posts. Best regards.
